Carbohydrates glycaemic index (GI)
Glycemic index estimates
carbohydrates containing food based on how they increase the glucose in the
body. Foods are rated by comparing them to a reference food. Foods with high glycaemic
index increases blood glucose than foods with average or low glyceamic index. When taking foods with high GI, low GI foods
should be combined with it in order to balance the meal. Examples of low GI
foods are corn, most fruits, and yam. Medium GI foods include pita bread and
whole wheat. Puffed rice, instant oatmeals are examples of foods with high GI.

The skeletal muscle is one of the three types of muscle in the organism. <em>Option a) is correct. From smallest to largest, the parts of a </em><em>skeletal muscle </em><em>are Myofilament, sarcomere, myofibril, muscle fiber, fascicle, muscle. </em>
<h3>
The skeletal muscle</h3>
- It is the most abundant muscle in vertebrates, constituting the somatic musculature.
- Among its many functions, it proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It also participates in<em> eye movements, respiration, mastication, deglutition, and phonation</em>.
- The skeletal muscle contracts voluntarily, and its response is fast.
- Cells composing the striated muscle are significantly longer and multinucleated. They arrange in bundles, where cells are parallel to each other.
<h3>Composition of skeletal muscle</h3>
- <em>Myofilaments </em>⇒ Actine and miosine
- <em>Sarcomere</em> ⇒ It is the functional unit with the contractile apparatus. Composed of the Z band, A and I bands, and H zone.
- <em>Myofibrilles</em> ⇒ They have the Functional units
- <em>Muscle fibers</em> ⇒ Surrounded by endomysium
- <em>Fascicle </em>⇒ Group of fibers surrounded by perimysium.
- <em>Muscle</em> ⇒ Group of fascicles surrounded by epimysium.
Hence, the correct option is a).<em> From smallest to largest, the parts of a </em><em>skeletal muscle </em><em>are Myofilament, sarcomere, myofibril, muscle fiber, fascicle, muscle.</em>
